SPECIFICATION forming part of Letters Patent No. 244,773, .dated July 26, 1881.

Application filed January 18, 1881. (ModeL) T 0 all whom it may concern Be it known that I, PAUL SINNHOLD, of St. Louis, Missouri, have made a new and useful Improvement-in Cultivators, of which the following is a full, clear, and exact description, reference being had to the, annexed drawings, making part of this specification, in which Figure 1 is a view in perspective of the im' proved cultivator; Fig. 2, a side elevation of the main wheel,the wheel-frame being partlyin section; Fig.3,aview of the bolt used in adjusting the friction-pulley against the main wheel; Fig. 4, a plan of the upper end of one of .the pitmen that'connect the friction-pulley and the seed-drill mechanism; Fig. 5, a side view of the same; Fig. 6, a view of the lower end of the pitman; Fig. 7, a perspectiveview of one of. the seed-hoppers; Fig.8, a central longitudinal section of the joint that connects one of the main beams to the plow-frame; Fig. 9, a vertical transverse section of the same; Fig. 10, a vertical section taken on the line 00 a: of Fig. 8; Fig. 11, a side elevation of one of the shovels and shovel-heads; Fig. 12, a plan of the parts shown in Fig. .11, and Fig. 13 a plan of the machine.

The same letters denote the sameparts.

The present invention relates to the means used in attaching the main plow-beams to the frame of theimplement. It also has reference to the mode of attaching the rear beams to the main beams; also, to the mode of attaching theshovels or plows to the beams also, to the manner of connecting the draft-rods to the beams; also, to the fifth shovel and parts immediately therewith connected.

Referring to the drawings, A represents the frame of the improved machine, consisting, mainly, of acentral beam, a, arranged longitudinally in the machine, and held in place by means of a forward wheel, B, and the main wheel 0. The beam is perforated to receive the forked arm 0 of the wheel G, as shown in Fig. 2, and the beam a, carrying the crossbeam D, can be adjusted vertically upon the arm 0, and in the following manner: A screw, 0, held in the top 0 of the arm a, engages with a nut, d, that is connected with the cross-beam D, and by suitably turning the screw the beams a D are raised or lowered accordingly. The forward end of the beam a is also vertically adjustable upon the arm I) of the wheel B. Braces or rods E E lead from the forward end of the beam at to the ends of the cross-beam D. The latter is in two parts--an upper plate, d, and lower plate, d and in the ends of the plates at d d shafts F F are held, the plates coming between the nuts (1 d and the collars d d respectively.

The main plow-beams G G are jointed to the shafts F F, and so as to turn thereon either up and down or laterally, or both up and down and laterally, or otherwise, as hereinafter explained.

H H represent two similar plates, that, by means of bolts h' h, are clamped around the balls f f of the shafts F F, the plates being suitably shaped at h h to fit the shaft F and balls ff. The clamps H. H thus havelateral and vertical motion upon the shafts F F; but to limit the motion in a vertical direction the plates are furnished with two stops, f 1, which are arranged to move in and out in a groove,f in the clamp, and by means of the screws f? f to be set closely against the shafts F F, as shown in the full lines in Fig. 8, or to be withdrawn therefrom. When both stops are against the shaft F the clamp can only be turned in a. horizontal plane; but when one of the stops, as f is withdrawn the clamp, by reason of the stop f has a limited motion in a vertical direction, and when both stops are withdrawn the clamps can be turned both up and down and laterally.

The main plow-beams G G are,'by means of the bolts h h, fastened to the clamps H H, and move with them. The beams G G may be made in two parts, g 9 adjustable longitudinally upon each other, the former part carrying the forward shovels, M M, and the latter forming the handles. The latter also supports the rear plow-beams, J J, which at s s are pivoted to the handles g 9 enabling them to be turned from the position shown inFig. 1 upward, so as to be entirely free of the ground, and so that the main beams can swing freely as desired. A tie-rod, K, aids in holding the rearbeam in position, extending from the clamp H backward to the beam J, the connection with the latter being by means of the springdog L; and to disengage the tie-rod K it is only necessary to throw out the dog L, when the beam J can be turned upward toward the main beam.

The shovels M M are made adjustable upon the beams both in a horizontal and in a vertical direction, the shovels being attached to the heads M M by means of the screws m m, and the back of the shovel bears against a rounded boss, m, that projects from the point of the head M. By suitably loosening the screw m upon one side of the shovel and tightening the screw upon the opposite side the shovel can be inclined to one side, and vice versa. The head M is pivoted at m to the end of the beam, and it, by means of the perforated plates m can be adjusted in a ve'Fti cal plane.

A fifth shovel, N, is held by a forked arm, a, that is journaled upon the bearings of the main wheel 0, and that extends across the wheel, and at n is provided with a scraperplate, 12 to prevent the dirt from being carried upward by the wheel 0 to the mechanism used in operating the seed-drill. A chain, n leads from the shovel N to the beam a, and serves both as a tie and as a means for adjustin g the shovel vertically.

O 0 represent the draft-rods leading from the tree 0 through the cross-piece 0 to the beam at 0 0that is, the rods connect with screws 0 0, that are screwed transversely through one of a set of perforations, 0 0 in the beam, and by screwing the bolts 0 0 into and out of the beam the latter is turned upon its bearing at the shaft F inward and outward accordingly, and by changing the screws upward and downward in the perforations o 0 the beams are caused to point downward or up ward accordingly.

The seed-drill portion of the mechanism is as follows:

P P represent arms pivoted at their lower ends to lugs or other bearings, 19 p, upon the arm 0, and at their upper ends connected by means of the screw-bolt p with the beam a, the boltp', at its upper end, being held in the beam a, as indicated in Fig. 3, and at its lower end engaging in a cross-bar, 11 that is held loosely in the arms P P. By turning the bolt the arms 1 P are turned upon the bearings 1) 1) up or down accordingly.

Q, represents a friction-wheel attached to the shaft g, which, in turn, isjournaled in the arms P P. By raising the latter thewh eel Q is brought in contact with the wheel 0, and thereby caused to rotate. The shaft q is provided with cranks q g, each of which, by a ball-and-socket joint, is connected with a pitman, R. The latter, at

its lower end, is jointed to a slide'bar, S, causing it to move forward and backward as the machine is moved along.

T T represent seed-boxes attached to the plow-beams. The boxes are furnished with openings (not shown) through which the seed drops into the conductor-spouts U U. The slides S, as they are moved forward and backward, open and close the seed-box openings and regulate the dropping of the seed. The spouts deliver the seed just behind the shovels in plain view, enabling the operator to readily inspect the operation.

I claim- 1. The combination of the beam a, wheel B, wheel 0, arm 0, rods E E, and cross-beam D, substantially as described.

2. The combination of the cross-beam D,

shafts F F, and plow-beams G G, said beams being jointed to said shafts, substantially as described.
